Leidt? DEMONTABLE SPRING RIM FOR VEHICLE WHEELS.

Application filed March 10, 1923. Serial No. 624,177.

To all whom t may concern.'

Be it known that I, JOHN ARRENBRECHT, a citizen ot' the United States,residing at Salem, in the county of Columbiana and State of Ohio, haveinvented certain new and useful Improvements in Demountable Spring Rimsfor Vehicle Wheels; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The invention has for its object the provision of a spring rim adaptedto be applied to vehicle wheels where a yielding tread is required toneutralize shock and vibration and minimize the wear and tear upon thevehicle and the motive plant and connections of a mechanically drivenvehicle such as an automobile.

Other objects and advantages will be apparent and suggest themselves asthe nature of the invention is understood.

While the drawings illustrate an embodiment of the invention it is to beunderstood that in adapting the same to meet different conditions andrequirements, various changes in the form, proportion and minor detailsof construction may be resorted to without departing from the nature ofthe invention.

Referring to the. ,accompanying drawings forming a part of theapplication,

Figure 1 is a side view of a portion of a demountable spring rimembodying the invention, parts being broken away,

Figure 2 is a transverse section on the line 2-2 of Figure l,

Figure 3 is a cross section on the line 3--3 of Figure l, and

Figure l is a detail sectional view on the line 4--4 of Figure l.

Corresponding and like parts are referred to in thefollowinodescrip-tion and designated in the severa views of the drawingsby like reference characters.

The demountable rim comprisesv an inner ring l andan outer` ring 2, thetwo rings being spaced apart any determinate distance. Expansiblehelical springs 3 are interposed between the tworings and are normallyunder tension, said springs being retained in place by means of lugs 4Capplied to the rings. Links 5 disposed between adj acent springs 3operate to hold said springs in the required position. Clips 6 attachedto the-inner ring 1 extends inwardly to serve as means for securing therim as a whole to the felloe of the vehicle wheel, said clips beingapertured to receive the securing bolts. Brackets 7 are applied to therings l and 2 and links 8 are provided to coact with the brackets 7 andextend between tne rings l and 2 and prevent relative circumferential orlateral displacement of the rings. Plates 9 are applied to oppositesides of the rings l and 2 and close the space formed between them,thereby protecting the springs and the several connections between therings. The plates 9 are bolted to opposite sides of the outer ring 2 andloosely engage the sides of the inner ring l. El band l0 is bolted orotherwise secured to the outer side of the ring 2 and has a tire l1cemented or otherwise secured thereto.

The rim is designed to be applied to the "i vehicle wheel of anautomobile to replace the usual pneumatic tire, thereby overcoming theobjectionable features such as puncture, blowout and rim cut.

What is claimed is:

l. A demountable rim comprising spaced inner and outer rings, interposedexpansible helical springs connecting the said rings, links between eachtwo adjacent springs and having their ends pivotally connected to theadjacent springs, brackets applied to the rings, and crossed linkspivoted to and coacting with the brackets and forming connecting meansbetween the rings.

2. A demountable rim comprising spaced inner and outer rings, interposedeXpansible helical springs, connecting the said rings, links betweeneach two adjacent springs, and said links having their ends pivotallyconnected to the adjacent springs, to hold the same in their requiredposition.

In testimony whereof I atlix my signature in presence of two witnesses.
